Janna was one of the last few key users of Glacial Augment, but they removed her E healing and shielding power passive (= weaker slows on Glacial) and reverted her to be a poke champ with W max again, resulting in Arcane Comet becoming the better choice.

This change makes the Inspiration tree even more of a failure. To date 2/3rd (8 out of 12) of the runes are barely used.

  1. Glacial Augment: only a very few tank supports use it as their keystone, for which the rune is definitely not designed (as they nerfed it 2 times to have a lower base slow and better scaling with H/S power and AP). So basically none of the intended users (enchanters) still uses this keystone rune.
  2. Unsealed Spellbook: not a single key user, completely dead keystone rune.
  3. Hextech Flashtraption: used by a very few tank supports, not a single other class uses it.
  4. Biscuits Delivery: nerfed to the ground. It gives almost NOTHING. If you are below 20% hp and mana at level 10, it gives ~100 hp and ~40 mana, it you use it at level 5, it gives ~65 hp and ~25 mana. That’s ridiculously bad for a rune.
  5. Future’s Market: used to be quite good on junglers to get that early power spike after a full clear (enough gold for Dirk, Whip or Sorcs), but after the nerf - which made this tactic impossible - it’s basically a very weak rune. Other classes don’t use it anyway.
  6. Minion Dematerializer: used by a very few mages. Basically just because they run First Strike (and thus are locked in the Inspiration tree) and find this the least weak rune on the 3rd row. Not because it’s particularly good.
  7. Approach Velocity: other than Tahm, Braum, Mundo and maybe Cho’Gath, I don’t see much users. It’s not even that noticable on them either, but ok at least it’s not completely unused.
  8. Time Warp Tonic: completely gutted rune. Not worth it to ever take it. Not a single champion goes it to date. The ones that do, is by accident.

You get my point? The Inspiration tree is dead. Why after 6 years of runes reforged is it so difficult to redesign some unused runes?
